[0001] The invention relates to a process for preparing a water-in-oil emulsion [e / h] comprising the following steps: a) dissolving at least one active principle selected from the group of topical corticosteroids in an oily phase； b) dissolving at least one preservative free of chlorocresol, in an aqueous phase and the temperature is raised to the - addition of the temperature of reversal of phase； c) mixing and homogenization of the aqueous phase into the oily phase； d) rise in temperature of the mixture obtained at the top of the temperature of reversal of phase； e) cooling of the mixture, characterized in that: - the concentration of a preservative, expressed in percentage by mass relative to the total weight of the emulsion is less than 5%； the steps a) and (b) are made independently and in any order. [0002] The invention also relates to the emulsion obtained by the process according to the invention and its use.
